Salt dome

A salt dome is a type of structural dome formed when rock salt (or other evaporite minerals) pushes into overlying rocks in a process known as diapirism. Salt domes can have unique surface and subsurface structures, and they can be discovered using techniques such as seismic reflection. They are important in petroleum geology as they can function as petroleum traps. Read by JohnAnkerBow. Recorded July 26, 2019; the article may have changed since.
